Color ram appears to be bad during the self test.


I desoldered the two 6116 rams used as color ram, however they appear to be good. This probably means an IC related to these rams is deffective.

However, i will have to put socket both and test with other rams so I can be sure they are working before testing the other ICs.

Found a bad 74LS245 @ U14

Actually, replacing the 74LS245 @ U14 fixed the problem
